HOLDER FOR WORK snnnrs Ann cannons.

Application filed February 6, 1922. Serial No. 534,364.

, The present invention relates to a permanent holder for carbon-sheets, of such character thatWork-sheets may be interleaved with the carbon-sheets in the holder, and the 6 latter with the assembled carbons and worksheets fed as a unit around the platen to printing position thereon.

An object of the invention is a holder of this general character, but of a construction 10 which provided aligning means for the edges of the work-sheets therein, and in which the carbons are so held that the worksheets have freedom of movement, between the carbons, to the aligning means. In the form of the invention, hereinafter shown,

the carbons are attached to the holder beyond'the work-sheet aligning means, so that the close contact of the carbons with the holder and with each other, adjacent the line of such attachment, may not impede movement of the work-sheets therebetween or render uncertain a true registration and alignment of the ed 'es of thelatter. A

fold in the holder in front of the line of attachment of the carbons thereto, and where the carbons are quite loose and free of the holder and with one another, provides a crease which may serve as the work-sheet aligning means; and, freedom of movement of the work-sheets to this aligning crease is assured by such looseness of the carbons.

A feature of the invention is the provision for suchfreedom of the carbon-sheets that the work-sheets may slide or be jogged down to aligned position; thus permitting a preliminary interleavement of the work-sheets with the carbons which requires little or no handling of the latter. To facilitate interleavement of the work-sheets, without handling the carbons, the latter are hereinafter shown as of graduated lengths, so that, when a pack of carbons is laid with the longest carbon at the bottom, steps are provided on which the edges of the work-sheets may be set and slid under the shorter overlying carbons. The graduations in length 0 the carbon-sheets also obviate the trouble and smudging of the fingers involved in separating and finding the ends of the proper carbons for insertion and removal of Work-sheets.

An ob'ect of the invention is the rovision 0 means for binding the lea ing 7 ends of the carbon-sheets, so that the same may not become spread apart, twisted or .in which the assembly is stood on end to crumpled; and so that, for insertion into the machine, the holder and the sheets assembled therein may present a flat, smooth, unitary leading edge, which will preclude possibility of slipping and loss of accuracy of alignment, as Well as crumpling at the ends of the sheets, in inserting the assemblage; the whole being in effect a unit inserter for all the sheets.

In general, an object of the invention is the provision of means to assist in developing speed, cleanliness and accuracy in assembling work-sheets and carbons, and in inserting the same into the machine.

Other features and advantages will here inafter appear.

In the accompanying drawings,

Figure 1 is a perspective view of the pack ofcarbon-sheets assembled in their holder with the work-sheets interleaved between; the assembly being shown in printing position on the platen.

Figure 2 is a perspective view of the pack of carbon-sheets assembled in their holder.

Figure 3 is a side view of the assembly shown in Figure 2.

Figures 4 and 5 indicate, diagrammatically, the process of interleaving the worksheets with the carbons for a preliminary setting of the former.

Figure 6 is a side view of the assembly. after the process indicated in Figures 4 and 5 is completed, and showing the manner permit the work-sheets to slide or be shaken down to final position between the carbons. Figure 7 is a side view of the assembled carbons and work-sheets in the holder, with the upper edges of the work-sheets aligned by the fold in the holder, and with the assembly ready for insertion into the typewriting machine.

As shown in Figures 2 and 3, carbonsheets 1, 2, 3 and 4, forming a pack, are of graduated lengths. Their upper edges indicated at 5, in Figure 3, are aligned, and are in alignment with one of the edges of each of two relatively stiff stri s 6 and 7 of paper. These strips 6 an 7 comprise a 1 holder for the pack of carbons. The carbon-sheets are shown as stitched at 8 to the strips 6 and 7 between which they lie. The holder, see Figure 3, is shown as having been folded at 9 after the stitching of the car- 1 bons thereto has been efiected. The fold 9 is located and is determined by one edge of the strip 7. In other words, the carbonsheets and the strip 7 are first laid flat, with the edges of the carbon-sheets in alignment with what are then the upper edges of the holder-strips 6 and 7, and the stitching effected; after which the carbon-sheets and the strip 6 are folded around the strip 7 on the line of what was previously the lower edge of the strip 7. It will be noted that 'the strip 6 is much longer than the strip 7, so that, as shown in Figure 3, it extends along the lower side of the pack of carbons, in the form of a flap, to the point 10. It should be understood that, inasmuch as the flap is on the carbonized side of the lower sheet, it is desirable to have this flap of considerable length so that the pack may be easily handled without soiling the fingers.

In the assembly as shown in Figure 3, the carbon sides of the sheets 1, 2, 3 and at are the lower sides. In interleaving the work-sheets 15, in the manner shown in Figures 4 and 5, the sheet which is to receive its impression from the ribbon is placed on top of the carbon-sheet 1 and moved over the latter until its leading edge is aligned by the fold 9, or is, at least, within the fold of the holder. Other work-sheets are then successively interleaved with the carbonsheets, and, finally, a work-sheet may he slipped between the lower carbon-sheet 4L and the under flap of the holder-strip 6.

end, as shown in Figure 6, and the worksheets shaken down to the fold 9, which serves as a means for aligning their leading edges; the work-sheets being thus brought to the Figure 7 position, with the.

assembly ready'for insertion into the machine.

Thestiifness required for the process of inserting the work-sheets and for the process of shaking down and aligning the same is secured by the fold or crease in the holderstripfi, as shown in Figure 1. As this told or crease is parallel w1th the leading edges of the carbon-sheets and therefore parallel with the axis of the platen when in use in a typewriting machine, and as the sheets are joined by a single parallel line of stitching, the pack can readily be passed around the platen.

The sheets being assembled as shown in Figure 7 the holder, with the pack of carbons and interleaved work-sheets, may be inserted into the machine downward, be-

hind the platen 11, and fed around between the same and the feed-rolls 12, as shown in Figure 1, in the same manner as mi ht a single work-sheet. In Figure 1, a col ating board 13 is shown, having the usual upturned side flange 14 which may be used as a gage to position the carbon-and-work' sheet assembl and to'maintain the alignment of the side edges of the sheets beyond the holder.

It will be noted that the work sheets do not enterthe area where the carbons, because of the stitching, bear firmly on one another. The fold 9 in the holder is in advance or in front of the stitching, in the path of movement of the work-sheets to aligned positions; and the carbons are free and loose, with respect to each other, at the fold 9, so that, as indicated in Figure (3, they fall apart as far as the fold, to provide freedom of movement of the worksheets to the aligning means. The edge formed by the fold at 9 serves as the leading edge of the unit in insertion of the same into the machine. The holder at this point so binds the leading edges of the work-sheets that slipping and loss of accuracy of alignment of the latter, as the same are fed into the machine, cannot take place; and the holder also so binds the carbons and worksheets, at the leading edge of the unit, that the edges of the sheets therein cannot spread apart and be crumpled, but must present a fiat smooth leading edge for feed into the machine.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.

Having thus described my invention, I claim:

1. In a permanent holder for carbonsheets, the combination of a pack of carbonsheets, a stiii' paper strip bent over the leading edges of said pack, a line of stitching to join the .pack and the strip together, and a transverse fold of both pack and strip, each lower carbon-sheet in said pack being sufficiently longer than the" overl ing sheet to form a marginal guide for guiding a worksheet between the same and the overlying sheet.

2. The combination of a pack of carbon sheets and a holder therefor, said pack and holder having a transverse fold constituting means for aligning work-sheets, and means securing said sheets together beyond the fold.

3. In a permanent holder for carbon sheets, the combination of a pack of carbon sheets and stiff paper strip, said pack and strip being bent over to form a fold therein, and a line of stitching beyond said fold so curing together said pack and bent over portion only of said strip.
